Smart projector CPU comparison:Mstar VS Amlogic

Recently, more and more TV and projector brands use Amlogic T972-H chips, such as Xiaomi

Big Eye Orange, Tmall, and other projectors.

 

The Amlogic T972 chip uses a quad-core Cortex-A55 architecture, and GPU is upgraded from Mali-G31, supporting the latest OpenGL ES 3.2 and Vulkan 1.1 API.

 

Below you can find a comparison of previous generations of Amlogic TV chips:

We have reviewed the relevant information and summarized in vernacular the general classification of CPUs and GPUs as follows

 CPU:

The official interpretation of the A55 reads as follows.

 

The Cortex-A55 is built on the latest ARMv8.2 architecture and builds on its predecessor. It pushes the limits in terms of performance while still maintaining the same level of power consumption as the Cortex-A53. We have made every effort to improve the Cortex-A53 and give it the following features.

 

➤ Memory performance up to twice that of Cortex-A53 at the same frequency and process conditions

➤ 15% more efficient than Cortex-A53 at the same frequency and process conditions

➤ More than 10 times more expandable than Cortex-A53.

 

The positioning of the ARM Cortex Series 5 as "high efficiency" and Series 7 as "high performance" is a fact of life.

The Mali G31 has also improved its power performance compared to the T830. 

As you can see from the table above, the T972 is indeed an upgrade to the T968, but at the expense of the USB 3.0 port, it cannot yet be called a "replacement"

 At the same time, we also made a brief comparison of the staples of another giant in the TV chip industry, MTK (formerly Mstar)

By comparison, the Amlogic T968 and Mstar838 are basically at the same level, the T972 has a certain improvement in CPU compared to the Mstar838, but also due to the neutering of USB 3.0, it is hard to tell the difference. The Mstar 938 and 848 (8386 in business graphics) are Cortex7 series +5 series cores, and the GPU configuration is maintained at a high level, just like the Mstar 938 chip used in the Dangbei F1, which is another level.
